The best yarn for a sweater is one that suits the season and the fit you want: warm wool or a soft worsted for cozy winter knits, a lighter DK for layering, and breathable cotton for a summer top or cardigan. Drape and stitch definition matter more on a garment than on a blanket, and every Estako line below is OEKO-TEX® Standard 100 certified.

For warmth, reach for Happy Wool or plush Cozy. For classic worsted sweaters and colorwork, Star-Worsted and Megastar hold cables and Fair Isle cleanly, and Star-DK carries the same wool blend at a lighter DK gauge for cardigans and vests. Softy is the easy, lightweight pick for a no-fuss pullover, DailyKnit-DK and Downy work for lighter layering pieces, mercerized Royal Cotton suits a breathable summer top, and Cotton Life carries 361 yards on one 100 g skein, so a cotton-blend cardigan needs fewer joins. Bamboo Life shares that put-up with a rayon-from-bamboo blend, so a summer top or cardigan hangs with more drape.

New to choosing sweater yarn? Our sweater yarn guide and wool yarn guide walk through fiber and weight, and the how much yarn do I need guide turns a pattern's yardage into a real ball count.

Common questions

How many skeins do I need for an adult sweater?

Worked at each yarn's own published gauge, for a mid-size adult pullover:

  • Cotton Life, CYCA #2, 361 yds / 100 g: 5 to 8 skeins
  • Downy, CYCA #3, 267 yds / 100 g: 5 to 8 skeins
  • DailyKnit-DK, CYCA #3, 273 yds / 100 g: 6 to 9 skeins
  • Happy Wool, CYCA #1, 191 yds / 50 g: 6 to 9 skeins
  • Star-Worsted, CYCA #4, 186 yds / 100 g: 7 to 11 skeins
  • Megastar, CYCA #5, 120 yds / 100 g: 8 to 12 skeins
  • Softy, CYCA #5, 98 yds / 100 g: 11 to 16 skeins
  • Cozy, CYCA #6, 65 yds / 100 g: 13 to 18 skeins
  • Royal Cotton, CYCA #1, 137 yds / 50 g: about 25 skeins

Royal Cotton is the outlier because a fingering-weight cotton garment needs a lot of yardage. Size, ease and stitch pattern move all of these, so treat them as a starting point and check against your pattern.

Which weight should I pick for a sweater?

Warmth and season decide it. Happy Wool is CYCA #1 Super Fine with 40% Merino wool, for fine winter knits that hold shape. Cotton Life is CYCA #2 Fine / Sport and breathes, which suits a summer top or a lightweight cardigan. DailyKnit-DK and Downy are CYCA #3 for layering pieces. Star-Worsted is CYCA #4, the classic sweater weight that holds cables and colorwork cleanly. Megastar and Softy are CYCA #5, and Cozy is CYCA #6 for a fast, thick winter knit.

Drape and stitch definition matter more on a garment than on a blanket, so swatch before you commit, and block the swatch the way you plan to wash the finished piece.

Which of these can I machine wash?

All nine can go in a machine, but the wool blends want more care:

  • Happy Wool (40% Merino wool): hand wash, or machine wash cold on a gentle wool cycle. Lay flat to dry. Do not wring or tumble dry. Reshape gently while damp.
  • Star-Worsted (75% acrylic, 25% wool): cold gentle cycle or hand wash, then lay flat to dry and reshape while damp. Avoid wringing and direct ironing.
  • Megastar and Cozy (75/25 and 80/20 acrylic and wool): cold, gentle cycle, lay flat to dry. Do not iron directly.
  • DailyKnit-DK: cold or warm, gentle cycle, lay flat or tumble dry low.
  • Downy, Softy, Royal Cotton, Cotton Life: cold or cool, gentle cycle. Softy can tumble dry low. Cotton Life should not be tumble dried or ironed.
Do I need to buy all my yarn in one dye lot?

For a garment, yes. Dye lots rotate, and two skeins of the same color from different lots can read as slightly different shades across a sleeve or a yoke. Work out your total first, then order the whole amount at once, plus one spare skein if the budget allows. A leftover skein is cheaper than an unfinished sweater. There is more on this in our dye lots guide.
